Disclosed may be a method of controlling a valet mode of a vehicle, the method including determining whether the vehicle may be in valet mode, when the vehicle may be determined to be in the valet mode, setting the vehicle to a plurality of parking state modes based on the traveling state of the vehicle being parked, and calculating an air conditioning limit power capable of limiting the air conditioning of the vehicle based on each of the valet mode and the plurality of set parking state modes.

The present disclosure relates to a method and a device for end position detection of actuators.

A control unit configured to operate remote air conditioning of a vehicle in response to a person being present in a rear seat of a parked vehicle and open a window of the vehicle in response to a remaining charge amount of a battery of the vehicle being less than or equal to a predetermined amount when the remote air conditioning of the vehicle is being operated.

A testing device characterizes a damper/valve in situ in a HVAC system. It comprises a controller including a processor and a memory and circuitry. The testing device is mounted on a damper assembly having a control shaft and a damper rotatably coupled to the control shaft such that the control shaft is activated by the circuitry of the testing device. The testing device further comprises computer-readable logic code to: open and close the damper by actuating the control shaft, detect a rotational position of the damper and a torque required to move the damper to the rotational position, characterize a plurality of torques required to drive the damper to a plurality of pre-determined rotational positions of the damper when subjected to a fluid flow to generate damper rotational position data vs. torque data, and store the damper rotational position data vs. torque data to produce damper characteristic graphs.

Disclosed is an air conditioner for a vehicle. The air conditioner for a vehicle includes: an air conditioning case including an air inflow port for introducing air, air discharge ports for discharging air into the interior, and an internal air passage formed therein; a cooling heat exchanger and a heating heat exchanger sequentially provided in the air passage of the air conditioning case in an air flow direction; and doors for adjusting the opening degree of the air passage in the air conditioning case via rotation, wherein an airflow control door is arranged downstream of a blower in the air flow direction, and is positioned adjacent to a cutoff region of a blower scroll case.

A system and method are provided for detecting humans or pets located within the interior of a vehicle and mitigating harmful environmental conditions within the interior to protect humans or pets that may have been inadvertently left inside the vehicle and are incapable of voluntarily exiting the vehicle. The system includes a vehicle having an interior space for occupants and an air conditioner for regulating the air temperature within the interior space. The system also includes a detection sensor for detecting whether a person or pet is inside the vehicle and an environmental sensor for detecting the air temperature inside the vehicle. If the system determines that a person or pet is occupying the vehicle and the inside air temperature is above or below a safe level, the system is designed to automatically take corrective actions to regulate the air temperature to prevent serious injury or death to vehicle occupants.

An air-conditioning vent structure includes a duct portion supported by a duct panel, the duct portion including first and second outlets formed at an upper portion thereof and separated by a partition, and a curvature portion including a curvature, a sliding door slidable along an upper portion of the curvature portion at a lower end portion of the partition, the sliding door including a hole to adjust opening widths of the first and second outlets in accordance with a degree of sliding, a driving portion connected to the sliding door at a lower end portion of the duct panel and configured to apply driving force to the sliding door so that the sliding door slides in opposite directions, and a controller electrically connected to the driving portion to perform a control operation to allow the sliding door to slide in opposite directions in accordance with a use mode.

An HVAC system for a vehicle is configured to draw air from an air inlet, to condition the drawn air, and to discharge the conditioned air to at least one discharge portion in the vehicle through a main flow path. The HVAC system includes a bypass flow path configured to connect a first side of the main flow path disposed at a side of the at least one discharge portion to a second side of the main flow path disposed at a side of the air inlet. The bypass flow path is configured to allow or block a flow of air through the bypass flow path.

A car air conditioning system has a pneumatic circuit to feed an air flow into a passenger compartment of a vehicle, and a cooling circuit to cool the air flow fed along the pneumatic circuit; the pneumatic circuit being provided with a three-way joint, which has an inlet connected to a first pneumatic duct, a first outlet connected to a second pneumatic duct, a second outlet communicating with the passenger compartment of the vehicle, and a shutter, which is movable from and to a closing position, wherein the inlet is separate from the two outlets.

A barrier door may include a section including an outer stationary portion and an inner movable portion disposed within the outer stationary portion, an actuator, and a controller. The actuator may move the inner movable portion between different positions to control flow of air between a protective enclosure and a volume outside of the protective enclosure. The controller may monitor one or more operating characteristics of the actuator and may modify an operational status of the actuator to control the flow of the air between the protective enclosure and the volume outside of the protective enclosure based at least in part on the one or more operating characteristics.
